List of all members.

Public Member Functions

 SigSet ()
 Default constructor creates SigSet object with an empty signal set.
 SigSet (sigset_t *source_)
 Copy constructor from source_.
 ~SigSet ()
 Destructor.
int empty (void)
 This function initializes a signal set to be empty, no signals in it.
int fill (void)

int add (int signo_)
 This function adds the signal numbered signo_ to the set.
int del (int signo_)
 This function removes the signal signo_ from the set.
int is_member (int signo_)
 Use this function to tell whether the signal signo_ is in the set.
 operator sigset_t * ()
